Mean relative gamma rank correlation is 0.847 and seizure onset AUC is 0.482 in first-minute SEEG pairs from 36 patients after common average reference
The study tests relative gamma power in public stereoelectroencephalography (SEEG) data. Common average reference gives a mean contact-rank correlation of 0.847 across two recordings per patient. Mean seizure onset zone (SOZ) label AUC is 0.482. AUC is the area under the receiver operating characteristic curve. The 95 percent confidence interval for mean AUC is 0.404 to 0.561. Common average reference raises mean AUC by 0.044 relative to the provided reference. The corrected p-value is 0.041. These findings apply to the stated first-minute samples, contact rules, score direction, and clinical labels. They do not establish clinical usefulness.

- usesWith a common average reference, early gamma change ranks agreed more between interleaved estimates than across two seizures in 31 SEEG patients
This study supplied context on interictal relative-gamma rank repeatability and clinical label agreement. The new analysis tests early seizure-to-baseline gamma change and the effect of temporal splits. No prior feature data or source code entered the analysis.
- Lower contact numbers gave higher mean seizure onset label AUC than higher gamma fractions in two 60-second SEEG samples from 36 patients
[Legacy relation: reproduces] Before the name exclusion, every archived patient gamma AUC is reproduced exactly from the contact features. A separate spectral implementation reproduces 432 gamma scores from fresh prefixes for one patient. This is computation verification, not an independent cohort replication.
- usesLower contact numbers gave higher mean seizure onset label AUC than higher gamma fractions in two 60-second SEEG samples from 36 patients
The study uses the archived contact features, pinned source metadata, EDF decoder, and signal retrieval recipe. These files enable the fixed number versus gamma comparison in all 36 patients.
